Isotopic studies of rare gases in terrestrial samples and natural nucleosynthesis ( Computer File )
2 editions published in 1991 in English and held by 8 libraries worldwide
This project is concerned with research in rare gas mass spectrometry. Using a two-pronged attack, we study fluids using a system (RARGA) designed for fluid analysis in bulk which is sometimes deployed in the field and a laser microprobe mass spectrometer for fluid inclusion studies. In 1991 the RARGA project continued monitoring helium isotope variations associated with renewed seismic activity in Long Valley Caldera and expanded our geothermal data base to include Lassen National Park. An important objective, continuing in 1992, is to understand better the reasons for somewhat elevated ³He/⁴He ratios in regions where there is no contemporary volcanism which could produce the effect by addition of mantle helium. To this end, 1991 saw continued efforts to understand variations in composition between fluids and associated reservoir rocks and extended the data base to include fluids from the Gulf of Mexico. Our DOE work in calibrating a sensitive laser microprobe mass spectrometer for noble gases in fluid inclusions continues with successful returns particularly in calibrating neutron irradiated samples for tracing halogen ratios. In connection with observations of neutron-produced noble gas nuclides in granites, we have begun comparing measurements with calculations for both thermal and epithermal neutrons. We submitted a third paper on noble gases in diamonds, concentrating on observed effects of ⁴He, ³He, and fission xenon implantation from nuclear processes in adjacent material in the matrix rock. 16 refs., 1 tab
[Medium energy meson research] ( Computer File )
2 editions published in 1992 in English and held by 8 libraries worldwide
The activities of this group are primarily concerned with experiments using the Crystal Barrel Detector. This detector is installed and operating at the Low Energy Antiproton Ring (LEAR) at CERN. QCD, the modem theory of the strong interaction, is reasonably well understood at high energies, but unfortunately, low-energy QCD is still not well understood, and is far from being adequately tested. The Crystal Barrel experiments are designed to provide some of the tests. The basic line of research involves meson spectroscopy, analyses bearing on the quark and/or gluon content of nuclear states, and the exploration of mechanisms and rules which govern p[bar p] annihilation dynamics. The Crystal Barrel Detector detects and identifies charged and neutral particles with a geometric acceptance close to 100%. The principal component of the detector is an array of 1,380 CsI(TI) crystals. These crystals surround a Jet Drift Chamber (JDC), located in a 1.5 Tesla magnetic field, which measures the momentum and dE/dx of charged particles. One of the very interesting physics goals of the detector is a search for exotic mesonic states -- glueballs and hybrids. Annihilation at rest will be studied with both liquid and gaseous hydrogen targets. The gaseous target offers the possibility of triggering on atomic L-shell X rays so that specific initial angular momentum states can be studied. These topics as well as other related topics are discussed in this report

2 editions published in 1971 in English and held by 7 libraries worldwide
Studying dark energy with supernovae now, soon, and the not-too-distant future by Saul Perlmutter( visu )
3 editions published between 2003 and 2012 in English and held by 6 libraries worldwide
Dr. Saul Perlmutter, Lawrence Berkeley National Laboratory, talks about supernova measurements of the universe's (accelerating) expansion history. The next-generation measurements must take us a dramatic step forward in constraints on systematic uncertainties, since the previous measurements already have statistical uncertainties that are close to the current systematics limits. He shows how some recent results set the stage for these advances, and describes a series of ground- and space-based projects and a new satellite experiment (the SuperNova / Acceleration Probe, "SNAP") that promise a systematics-controlled prize: a detailed expansion history of the universe that can teach us about the nature of the mysterious "dark energy" that accelerates the universe

Control of quantum systems for information processing by K. Birgitta Whaley( visu )
2 editions published between 2003 and 2012 in English and held by 5 libraries worldwide
Prof. K. Birgitta Whaley, Dept. of Chemistry, UC Berkeley, spoke about the physical realization of quantum information processing which sets daunting challenges for control of interacting quantum systems. After outlining the requirements for such control to provide the large-scale quantum logic required for algorithmic speedup, she describes some advances in theory of implementations. Applications are given to gas-phase and solid-state implementations
Imaging the early universe with ACBAR by William Holzapfel( visu )
2 editions published between 2003 and 2012 in English and held by 5 libraries worldwide
Prof. William Holzapfel, Physics Dept., UC Berkeley talks about the Arcminute Cosmology Bolometer Array Receiver (ACBAR). Primary anisotropies of the Cosmic Microwave Background (CMB) encode a wealth of information about the early Universe. Recent degree-scale experiments have begun to exploit the potential of the CMB as a precision probe of cosmology with encouraging results. High-resolution images of the CMB can be used to provide improved constraints on cosmological parameters and study the growth of structure in the Universe. ACBAR is a powerful new instrument designed to image the CMB with resolution of 5 arcminutes. ACBAR was deployed to the South Pole in December 2000, and has recently produced the most sensitive images of the CMB of any experiment to date. He discusses the construction and operation of the receiver, and presents the key results from the first two years of observations
P.A.M. Dirac and the invention of quantum mechanics by Kurt Gottfried( visu )
2 editions published between 2003 and 2013 in English and held by 5 libraries worldwide
Prof. Kurt Gottfried, Dept. of Physics, Cornell University, motivated by the centenary of Dirac's birth, describes his role in the discovery and development of quantum mechanics. The emphasis is on his work prior to his discovery of the relativistic wave equation in 1928
Studying the structure of the space-time and the brain with atomic magnetometers by Michael Romalis( visu )
2 editions published between 2003 and 2012 in English and held by 5 libraries worldwide
Prof. Michael Romalis, Dept. of Physics, Princeton University, describes recent advances in the ultra-sensitive alkali-metal and noble gases magnetometers that allow them to compete in sensitivity and spatial resolution with most sensitive SQUID magnetometers. Several applications of such magnetometers for tests of fundamental symmetries, detection of biological magnetic fields, and NMR are discussed. They have developed a self-compensating co-magnetometer using an alkali-metal and a noble gas that is only sensitive to anomalous spin couplings beyond the Standard Model, which can be caused, for example, by non-commutativity of space-time. They have also demonstrated localization of magnetic fields using a multi-channel magnetometer and are developing a system for mapping of the magnetic fields generated by the brain
The roles of symmetries in nature by B Zumino( visu )
2 editions published between 2003 and 2012 in English and held by 5 libraries worldwide
Prof. Bruno Zumino, Physics Dept., UC Berkeley discusses symmetries, which play a very important role in nature. Some of these (e.g. mirror symmetry, time reversal and the symmetry that relates particles to antiparticles) are described by discrete transformations. These are not independent of one another, but are related by an important property of space-time that is implied by Einstein's theory of relativity. Other symmetries involve smooth transformations; some are only approximately valid, but are still very useful for an understanding of nature. There are also speculated symmetries, of which the most important is called supersymmetry, and relates the properties of very different particles. In spite of the lack of direct experimental evidence, there are compelling arguments for its validity. In theories such as string theory that attempt to unify quantum mechanics with Einstein's gravity, a new concept emerges to replace in part that of symmetry, the concept of duality
From high-energy neutrino astrophysics to abrupt climate change to microbial immortality by Paul Buford Price( Computer File )
2 editions published between 2004 and 2012 in English and held by 5 libraries worldwide
Prof. P. Buford Price, Dept. of Physics, UC Berkeley gives a talk suggesting how to parlay crazy ideas into discoveries in seemingly unrelated fields. He states, in the 1960's, Fleischer, Walker and I exploited the crazy idea that molecules and lunar minerals might permanently register the tracks of nuclear particles. Spinoffs of that idea included fission-track dating, Nucleopore filters, and radon monitoring in homes. The AMANDA high-energy neutrino observatory at the South Pole was born as the result of two of my students hearing a talk by Francis Halzen and deciding to measure the transparency of polar ice. The success of AMANDA and the decision to fund the IceCube observatory hinged on our understanding how micron-size dust particles scatter and absorb the Cherenkov light that makes neutrino astronomy feasible. The first spinoff of AMANDA was our Dust Logger, which fits down a borehole in 3000 m of polar ice and has enabled us to relate the dust particle record to climate change and to confirm the important role of volcanic eruptions as a driver of abrupt worldwide climate change. A second spinoff is our microbe logger, which has been deployed in Lake Tahoe and South Pole ice and may some day go to Mars and Jupiter's moon Europa. It probes microbial life and death in ice at temperatures down to -90°C (if it exists). A third spinoff is our Acoustic Televiewer, which can measure air bubble sizes in ice and derive surface temperature in the past. A fourth spinoff is our use of atmospheric muons to measure the flow rate of ice at very low temperature, reminiscent of Luis Alvarez's search for hidden chambers in the pyramids. Surprisingly, three of these new devices will help in construction and operation of IceCube
Inelastic electron tunneling implications for nanoscience by Wilson Ho( visu )
2 editions published between 2003 and 2012 in English and held by 5 libraries worldwide
Prof. Wilson Ho, Depts. of Chemistry and Physics/Astronomy, UC Irvine, explains that the spatial proximity required for electron tunneling enables the extraction of fundamental physical properties. The scanning tunneling microscope further confines tunneling in the other two dimensions. By focusing on the minor inelastic tunneling events, elementary excitations and light emission can be probed at sub-nanometer scale
Mysteries of the Eagle Nebula by Dmitry Ryutov( visu )
2 editions published between 2003 and 2012 in English and held by 5 libraries worldwide
Dmitry Ryutov, Senior Scientist, Lawrence Livermore National Laboratory, speaks about the Eagle Nebula with its grandiose pillar-like structures, one of the most beautiful astrophysical objects. More importantly, it is thought to be one of the "star nurseries." Attempts to explain the observed structures often lead to paradoxes and inconsistencies. In this talk, he summarizes the existing difficulties and describes possible ways of overcoming them, including possible laboratory experiments that would imitate the Eagle Nebula dynamics
Reflections, advice, and diversions, or Falling honey and floating logs by J. D Jackson( visu )
2 editions published between 2000 and 2012 in English and held by 5 libraries worldwide
After some perhaps revealing personal anecdotes, Prof. J.D. Jackson, Professor of Physics, University of California, Berkeley, comments on present flaws in physics education, as he sees them. Then he takes the audience in directions it does not take in the classroom, and discusses diverse and interesting phenomena, with some demonstrations. The aim is to imspire young physicists to be generalists, interested in and capable of explaining at least the essentials of every physical phenomenon
An atomic abacus trapped ion quantum computing experiments at NIST by Brian DeMarco( visu )
2 editions published between 2003 and 2012 in English and held by 5 libraries worldwide
Dr. Brian DeMarco, Post-doctoral Research Fellow, NIST describes their current work. Trapped atomic ions are an ideal system for exploring quantum information science because deterministic state preparation and efficient state detection are possible and coherent manipulation of atomic systems is relatively advanced. In their experiment, a few singly charged Be ions are confined by static and radio-frequency electric fields in a micro-machined linear Paul trap. The internal and motional states of the ions are coherently manipulated using applied laser light. Their focus is on demonstrating the necessary ingredients to produce a scalable quantum computing scheme and on simplifying and improving quantum logic gates
Cavity quantum electrodynamics with single atoms by H Walther( visu )
2 editions published between 2003 and 2012 in English and held by 5 libraries worldwide
Prof. Herbert Walther, Director, Max-Planck-Institute für Quanten Optik, discusses the micromaser, which is the most fundamental system to investigate the radiation-atom interaction. A single atom is interacting with a single mode of the radiation field. Besides the quantum features of the dynamics in the photon exchange between field and atom being investigated, also a steady-state field is generated in the cavity with non-classical properties, and even number states of the radiation field are generated. In the second part, experiments with trapped ions in cavities are discussed, allowing interesting applications in connection with quantum computing and quantum information
